, .T r/,ZZ whom it may concern,.-

Be it known that I, Isaac WHTTTEN WAL- TER, of Newberry, in the countyof Newberry and State of South Carolina, have invented certain new anduseful Improvements in Cburns; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, marked thereon, which form partof this specification, in which- Figure l is a side view of my inventionapplied to a churn. Fig. 2 is a central vertical section of the same online :r cv, Fig. l. Fig. 3 is a horizontal section on line y y, Fig. l.Figs. et and 5 are details.

This invention relates to improvements in churn attachments, and hasespecial reference to that class by which the agitating of cream inalternate opposite directions is effected; and it consists in the novelconstruct-ion and arrangement of the parts hereinafter described, andpointed out in the claim.

In the drawings, A represents the east-iron upright frame, whichsupports the churndasher and its actuating mechanism. This frame is ofsufficient height to admit of a vessel in which the milk is to bechurned to rest beneath its top bar upon a door or board, A', to whichthe lower ends oi' the frame A are suitably bolted.

To the side pieces, a a, of frame A, near the center thereof, are boltedthe ends of a strip or band of metal, b, which is bent in proper shapeto hold therein onehalf of a churn-can. At one side of the can, on bandb, is suitably hinged a strap, b', the free end of which is adapted tobe connected to the band b by a suitable adjustable retaining device atthe opposite side of the can, as shown in the drawings.

By means of bands b and b it is obvious that cans or vesseis ofdifferent diameters may be securely held in position within the frame 'Aduring the operation of churning, and may be easily and readily removedtherefrom when desired. The preferable manner of forming the saidretaining device is by so connecting the hinge end of strap b to strap bthat it will open easily outward. Then, by introducing the headed boltorscrew b through openings in and to the letters of referencethestraight extensions b5 b* of the straps b l1', and putting on thethreaded end of the said bolt a thumbnut, b5, the straps can oe openedor closed to receive cans of varying diameters. From the upperhorizontal bar, a', of frame A, over the center thereof, rises aninverted Y-shaped bracket, C, which is cast integral with the frame, thebifurcations of this brach et forming, with bar a', an opening, G2, inwhich plays a pinion, D, hereinafter referred to. The upper end ofbracket C is formed into a proper bearing for the journal of a segmentalrack, F, hereinafter described.

Atthe top of opening C2 is formed, in bracket G,a verticaljournal-bearing for the upper end of a short shaft, C', which has itslower journal in a bearing formed in the bar a. On this shaft C', abovebaro', is secured a pinion, D, which serves both to support the shaftvertically and rotate the same. The lower end of shaft C passes throughbar a', and is formed into a socket, c, angular in cross-section, andprovided with a thumb-screw or similar device for securing the upper endof the churndasher E within the saine, asshown.

F designates a segmental rack, which has its bearing j ournaled in theupper end of bracket C, as described, and suitably secured therein by awasher and nuts. The rack is preferably but a quarter of a circle insize, and its cogs engage the pinion D when in position, and therebyactuate the same when the rack is vibrated by means of its handle d.This handle d may be cast integral with rack F; but is preferably madeseparate and bolted thereto, as shown. This admits of a new handle beingsubstituted should the old one be broken without necessitating thepurchase of both handle and rack. The outer arms, ff, of rack Fareprovided with lugs f', which impinge on a flange of bracket C, as shown,and serve to prevent the rack from being forced out of engagement withpinion D when the rack is vibrated.

G designates a short bracket, adapted to be secured to the side of thebar a within the bifurcations of brackets C. This bracket Gis formedwith an upward extension or arm, g, which is preferably cast integralwith the saine, but may be made separate and secured thereto. This arm gacts against the lower outer side I CC of the rack -F, and serves toprevent the rack from becoming disengaged from pinion D, as shown.

rIhe churn dasher E ispreferably of the form shown in Fig. l," with twoor more depending arms or beaters, c', which gradually lessen inthickness from top to bottom. The upper end, e, of the dasher is formedto correspond with the interior of the socket c, in which it is securedby the described means. It will be observed that the lower ends of thedasherblades are unsupported in the churn-can, and that thereforevarious kinds and sizes of cans may be used. On the part e, below thesocket 0, may be placed a washer, e`, which prevents splashing of milkupon the operator.

The operation of the invention is as follows: The can or vesselcontaining the milk to be churned is placed in position within the frameand secured by the bands, as described. The

dasher, having the cover ofthe churn slipped I contemplate making theframe, as de- 3o scribed, with its accompanying parts, and selling thesame as an article of manufacture independent of the milk vessel orchurn.

I am aware that churn attachments have been made combining some featuresof the invention. Therefore I make no broad claims; but,

Having described my invention, I claim- The combination of the cast-ironframe A, having a base, A', and securing-bands b b', and Y-shapedbracket C, cast integral with the frame, segmental rack F, provided withstoplugs f', journaled in the upper end of said bracket shaft C',journaled in the lower portion of bracket C and in the top bar of theframe, pinion D, engaging rack F, a suitable retaining device formed onthe end of shaft C', for securing the churndasher thereto, and bracketG, having an arm, g, to prevent 1ateral disengagement of the rack andpinion, all substantially as and for the purpose specified.

In testimony that I claim the foregoing as myown I affix my signature inpresence of two witnesses.
